I am reloading for a West German 220 Sig. My standard load is 5.5 gr of HP-38 and a 230 Gr. plated bullet. However, I decided for back country in Wyoming I would load a more powerfull round. I have loaded according to Hornady their 230 Gr hard ball and 230 gr H.P. behind 7.4 Gr of Power Pistol. So I thought I would replace the standard recoil spring with a Wolff 22 Pound one. This cycles 100 percent. Am I thinking right about this?

I don’t shoot 230 grainers in my folded slide Sig 220 so don’t have a recipe using them and PowerPistol. I checked Ammoguide and it seems 7.4 grain not max though likely full power. Any pressure signs? I usually go with Sig OE springs but the Wolff springs are great. I especially like their magazine springs. i think you are in fine shape maybe 400 foot pounds of energy.

What is the reason you do not use 230 Gr in your folded steel 220. Should I be concerned?

I think I was not clear on my first post. I already have the Wolff 22 pound recoil spring and it cycles both of my stated loads 100%.

If you don't find something that works for you - you could experiment with a hardcast Keith style bullet at lower velocity if it will feed. I would think it would handle the two legged and four legged critters.

I am not looking for 900 FPS just something with a bit more power then the normal loadings with a 230Gr. The 7.4 Gr of Power Pistol that I loaded has more recoil then the standard stuff.Using the 22 lb. Wolff recoil spring gives me 100% reliability. If I went with a 230 Gr. hard cast what would be a good load. I have both Unique and 2400?

No concern I just never got into shooting the flying ashtrays. Likely because I always saw better velocity and hence energy with the 185s. Hard to go wrong with a P220 in 45 ACP. Now with my all steel frame 220 the 230s might be an option. Not recoil sensitive but like being able to do controlled pairs, the extra weight helps.

Check the Alliant website, IIRC their load with PP is 8.1 with 230s, not rated +P either. I did a ladder test with it a couple years ago, and 8. anything is pretty stout. I settled on 7.5 as being plenty stout enough. The accuracy was great, velocity spread very low, about 7 fps I think. This was done using Hornady 230 gr XTPs. Good carry load.

Thanks that is what was needed. I used to use PP and loved it and then Obama and used up my 4 pound jug and then Long shot was available first. May have to go back to it.

Pardon the inaccuracy but I tend to use the "Keith style" description to describe any HC flat lead nose bullet. Although that Keith bullet is a great revolver and lever gun load - it takes quite a bit of experimentation and research to make one work in a 220. I've never loaded up HC lead for any of my 45ACP but I am sure there are some suitable HC FP loads that would be of great benefit for you.
